Clean, biodegradable structure for stem cell growth

Clean, biodegradable structure for stem cell growth
Medical scientists were shocked to discover that virtually all human embryonic stem cell lines being used in 2005 were contaminated. Animal byproducts used to line Petri dishes had left traces on the human cells. If those cells had been implanted in a human body they likely would have been rejected by the patient's immune system. Even today, with new stem cell lines approved for use in medical research, there remains a risk that these cells........Go to the Research news blog (Added on 2/3/2010 7:33:16 AM)


Curing More Cervical Cancer Patients

Curing More Cervical Cancer Patients
Cervical cancer is highly curable when caught early. But in a third of cases, the tumor responds poorly to treatment or recurs later, when cure is much less likely. Quicker identification of non-responding tumors appears to be possible using a new mathematical model developed by scientists at the Ohio State University Comprehensive Cancer Center-Arthur G. James Cancer Hospital and Richard J. Solove Research Institute. The model uses........Go to the Cervical cancer blog (Added on 2/1/2010 8:23:07 AM)

Over a two and half year period, beginning in 2005 when the U.S. Food and Drug Administration's oncology drug product's office began reviewing marketing applications, a total of 60 new oncology and hematology drugs were evaluated, of which 53 were approved, as per a new article published online January 29 in the Journal of the National Cancer Institute To provide an overview of recent regulatory actions by the FDA's Office of Oncology Drug........Go to the Cancer-blog (Added on 2/1/2010 8:18:00 AM)


Multiple sclerosis and the season

Multiple sclerosis and the season
Prior studies have shown multiple sclerosis (MS) patients are more often born in spring than in any other season, indicating that there is an environmental risk factor for the disease. A paper in the journal Neurology, evaluated for f1000 Medicine by Emmanuelle Waubant and Ellen Mowry, now suggests that this seasonal effect is mediated by the gene HLA-DRB1. In a number of European populations, the HLA-DRB1*15 allele of this gene is linked to........Go to the Neurology news blog (Added on 2/1/2010 8:14:45 AM)

Most patients gain weight after getting a new knee
You'd think folks who've had knee replacement surgery -- finally able to walk and exercise without pain -- would lose weight instead of put on pounds, but surprisingly that's not the case, as per a University of Delaware study. Scientists Joseph Zeni and Lynn Snyder-Mackler in the Department of Physical Therapy in UD's College of Health Sciences observed that patients typically drop weight in the first few weeks after total knee arthroplasty........Go to the Rheumatology news blog (Added on 2/1/2010 8:04:22 AM)

Stopping Schizophrenia Before It Starts?
The onset of schizophrenia is not easy to predict. Eventhough it is linked to as a number of as 14 genes in the human genome, the previous presence of schizophrenia in the family is not enough to determine whether one will succumb to the mind-altering condition.

How pancreatic cancer able to defeat drugs

How pancreatic cancer able to defeat drugs
Scientists at the Moores Cancer Center at the University of California, San Diego, have found one reason that pancreas cancer tumors are so difficult to treat with drugs. They have shown how a molecular switch steps up pancreas cancer cell survival as well as resistance to a standard chemotherapy drug, and have identified alternate routes cancer cells take to avoid the effects of the treatment.
